ARTIGULATED HOSE DERRICK Filed Nov. 23, 1962 4 Sheets-Sheet 4 INVENTOR. Edward S. Sheiry ATTORNEY.

United States Patent 3,228,421 ARTZCULATED HQSE DERRICK Edward S. Sheiry, 18 Wellyn Road, Bronxville, N.Y. Filed Nov. 23, 1962, Ser. No. 239,517 7 Claims. (Cl. 137615) This invention relates to marine hose derricks and ap purtenances for supporting, simultaneously manipulating, and positioning a plurality of pipe and flexible hose conduits extending from a stationary or relatively stationary terminal, to a point of coupling and uncoupling the assembly to manifold means for transferring fluid to and from said terminal, and it constitutes the provision of improvements in the subject of my patent, No. 2,922,446. The invention is particularly adapted for handling and effecting conduit connections between short terminals and ships manifolds. Such short outlets are generally on wharfs or piers, and because of the great weight of hose-conduits, their unwieldly nature, and the effect of wind and tides, the function of handling and accurately positioning and aligning the outer ends of the hose for connection with a ships manifolds without great manual effort, involves many problems which are overcome by the present invention, and whereby large dimensioned hose of great weight may be quickly and accurately positioned, so that they may be secured to receiving manifolds while held in position, regardless of the height or angle of the ships deck with relation to the wharf, pier or other terminal.

The invention will be described with reference to the accompanying drawings, in which:

FIGURE 1 is a side elevation, showing by full and dotted lines the pivoted primary boom and auxiliary boom in raised position, and also when lowered to a degree by which the hose is connected to the manifold means of a tanker, the latter being diagrammatically shown. The view includes a tower and its appurtenant elements for operating and counterweighting the primary boom and its auxiliary boom or booms.

FIGURE 2 is a rear view in elevation of the tower shown in FIGURE 1, taken on the line 22 of that figure.

FIGURE 3 is a view in elevation taken rearwardly of the primary boom on the line 33, FIG. 1, the upper portions of the boom frame being broken away.

FIGURE 4 is a partial side elevation showing empolyment of the auxiliary boom in supporting the hose at its swivel coupling means, while being coupled to a tankers manifold complex.

FIGURE 5 is a fragmentary view in front elevation showing the cross arm pivotally suspended from the outer end of the said auxiliary boom having trolley means for mutual side adjustment of a plurality of individual hose hoists, the trolley means and individual hose hoists being adapted for mechanical operation by a special tool assembly described hereinafter.

FIGURE 6 is a detail plan view showing the end of a hose and one of the triple swivel joint assemblies adapted for connection with a tanker manifold in accordance with FIGURES 1 and 4.

FIGURE 7 is a view illustrating a swivel joint construc tion employed between each of the fluid feed pipes, shown carried by the main boom in FIGURE 3, and leading to the hose.

Referring to the drawings, and particularly FIGURES 1 and 2, there is shown at 1 a rigid supporting tower which normally will be carried by a pier, wharf or other terminal point. The base of the tower carries a winch platform, as indicated in FIGURE 1, which may be reached by a ladder or stair arrangement indicated at 3. The primary boom 4 is carried on that face of the tower directly opposite a moored tanker or other fluid-receiving structure, and its opposed outer longitudinal arms (see FIGURE 3) have at their lower ends pivotal connections 5 providing swinging support of the primary boom on the tower. The pivots themselves may have longitudinal passageways for wire ropes.

In the embodiment of the invention shown in FIGURES 1 to 4, the primary boom carries longitudinally thereof a plurality of rigid pipe conduits 6, FIGURE 3, shown as four in that figure, and each conduit at its lower end is connected by a short length of flexible hose 7, to a conduit 3, FIG. 1, leading to a source of supply for the fluid. At its upper end each rigid pipe conduit 6 is connected to a swivel joint consisting of the members 9, 10 and 11, FIGURE 7, leading to a flexible hose 12, bolted to member 11 at 14.

At the outer end of hose 12, the latter carries a tripleswivel assembly for the manifold, through which oil or other fluid is purified from or to a tanker or other vessel. As shown in FIGURE 6, the triple-swivel arrangement employs 45

elbows

16 and 18, connecting swivel joints 17 which permit the assembly to rotate through degrees in all directions. By means of the flange 20, the hose may be bolted to a flange of the manifold pipe 21, FIG. 4.

On platform 2 is a motor 23, which may be electrical, hydraulic or air powered for driving a drum 25. A wire rope 27 has one end fixed to the drum 25 and thence leads over a pulley E at the top of the tower 1, thence over a pulley D on one side of primary boom 4 and thence the cable runs back to the tower and is fixed thereto. For the other side of the primary boom the same arrangement of a cable and pulleys will be employed, said second cable leading at its lower end from drum 25.

The primary boom pivotally carries an auxiliary boom which enables the derrick to move hose up and over the decks of the largest empty tankers at high tide, in which their fluid manifolds are at maximum height. Also, the auxiliary boom enables the derrick to so handle hose with respect to the manifolds of loaded vessels when at low tide, and this at their minimum height relatively to the wharf. The auxiliary boom, as to one side arm thereof, is indicated at 29, FIGS. 1 and 4. Its pivotal point of connection to the primary boom is indicated at 30. At least two side arms, as indicated at 29, are pivotally carried by the primary boom, one at each longitudinal frame member of the primary boom, and those side arms are connected by any suitable reinforcing beams and struts. At their outer ends, the side arms 29 of the auxiliary boom carry a trolley beam 31 (FIGURE 1), a face View of which is shown (partly broken away) in FIGURE 5.

Referring to FIGURE 5 of the drawings, it will be seen that the trolley beam 31 carries a worm shaft 32, which will be suitably supported in bearing members at its ends. On the base flange of trolley beam 31 are rollers 33 carried by a trolley arm 34, and trolley arm 34 carries a plurality of spaced brackets 35, one for each hose, four brackets being shown in the drawing at FIG- URE 5. Each bracket rotationally carries a winch having a drum indicated at 125, carrying a hoist rope 38, for a purpose later to be described.

Worm 32, carried by the trolley beam 31, carries at one end a bevel gear in a housing 39 and in which housing will be a customary and well known arrangement of said bevel gear in mesh with a driving bevel gear driven on a rotational connection 40, the latter carrying an eye member 443 adapted to receive the rotational hook end of a hand driving tool. The latter tools are well known in the art and are driven by either arm pressure or by electric power. Thus when the hook of such drive member is placed in the eye 40 rotation will be imparted to worm I 25 and 50, FIGURE 1, and with a dual valve or electrical switch device at 65 for selectively controlling the operation of the motors for said drums, from a tanker deck or other point such as a wharf adjacent a tanker.

Means are provided for compensatingly counterbalancing the boom structure in such manner that the cables connecting the primary boom with a principal and an auxiliary vertical-lift counterweight, are variably stressed in their varying inclinations, the arrangement including a hanger or hangers and a stop or stops acting upon the principal counterweight in such manner that the latter is caused to come to rest at a desired point along its vertical path of movement, so .that only the smaller counterweight provides further counterbalancing force on the boom structure, to which it is connected, during the remaining distance of movement of the boom structure.

The tower at its top rear area carries two pulleys 67 and 68 (FIGURE 2). FIGURE 1 shows that at the top of the tower cable 69 runs over pulley 67, thence over a pulley 67 and down therefrom to an arm on the primary boom projected rearwardly of the boom pivot point when the boom is upright. Cable 70 which runs over pulley 68 (FIGURE 2), will of course have corresponding guide and connection means to the primary boom. Refering to FIGURE 2, cable 69 is led downwardly from pulley 67 to and under a pulley 71, carried by an rrn 72 which extends through a passageway at 73, in the larger counterbalancing weight 74, arm 72 carrying the smaller counterweight 75. Cable 69, after leaving pulley 71, is led upwardly and fixed at its end to the tower 1, as at point 76. Cable 70 is led downwardly from pulley 68, thence around a pulley 77 on an arm 72*, the latter passing through the passageway at 73 in the larger counterbalance weight 74, said arm 72 being connected to smaller counterweight 75.

counterweight 74, in its lowest position, rests upon the stop seats 76, which may be provided therefor at any desired elevation; and in the embodiment shown, counterweight 74 is apertured to receive guide rails 78 carried by the tower. Also the lengths of the

cables

69 and 70 are suflicient to permit smaller counterweight 75 to hang any desired distance below the counterweight when the latter is inactive, as described.

When the boom structure-referring particularly to the primary boomis in vertical position, or substantially vertical position, the larger counterweight 74 will rest upon its stop seats 76, so that the tension on

cables

69 and 70 will be caused only about the weight of smaller counterweight 75, its

arms

72 and 72*, and sheaves or

pulleys

71, 77. In joint action referring to FIGURE 2, about one half of the weights of said elements is supported through the connection of

cables

69 and 70 with the fixed point 76 on the tower, and the other approximate half of the weights is carried to primary boom 4 to retard its gravitational movement downward under the influence of the auxiliary boom and the members carried thereby,

in addition to the effect of the tensions in

cables

69 and 70 which connect to primary boom 4 at a point behind its pivot 5.

When the tension on hoisting cables for the main boom is released, the boom structure will rotate downwardly, and smaller counterweight 75 will be moved upwardly by

cables

69 and 70, until it comes into contact with the larger counterweight 74. Further lowering of the boom structure will raise the large counterweight 74 to an elevated position as dotted line position in FIGURE 2. As the counterweights descend, th'e angularity of

cables

69 and 70 increases the stresses in them, thereby uniformly increasing sheer counterweight restraint on boom 4.

In the operation of the invention, when a tanker approaches a loading dock or wharf on which the tower and boom construction is mounted, the auxiliary boom, or both booms, may be raised to such positions that they will be clear of the tanker deck and superstructure. After the tanker is secured in position, the operator will manipulate the booms in such manner that the outer connections of one or a plurality of hose, is positioned with respect to its flange or their flanges, very close to the manifold or manifolds of the tanker. The precise levelling and positioning of the hose flanges relatively to the tanker manifolds, has been diflicult in the past when it is realized that a six or eight-inch hose, as to diameter, and twenty-five to thirty feet in length, will Weigh, along with its connections for a tanker manifold, many hundreds of pounds. This, together with motions of the vessel due to winds and tide, have created a problem overcome by the present invention. A substantially contributing improvement factor lies in my employment of a specially designed swivel pipe assembly at the end of hose carried by the boom assembly for connection to a tanker manifold or the like. As to be noted from either FIGURE 4 or FIGURE 6, the swivel section 16 is turned at an angle approximately 45 degrees relatively to its receiving swivel joint 17, and its companion swivel pipe section 18 is turned approximately 45 degrees on its receiving swivel joint 19. The large view in FIGURE 6 clarifies the double swivel connection, it being understood that members 17 are swivel joints,

members

16 and 18 each having swivel action in member 17.

In the use of the auxiliary boom of FIGURES 1 and 4, that boom being adapted to manipulate the hose, lowering of the auxiliary boom to position at FIGURE 4, and slightly inwardly from that position, will enable release of the hook member 108 from the eye member 106, as to each of the hose, and the auxiliary boom may be swung upwardly and away from obstruction to the deck of the tanker. Thus also, if at a given time, the fluid pumping action is required for only one hose, the other hoses may be hooked onto the auxiliary boom and raised, thus clearing the tanker deck of an unnecessary obstruction.

In the invention a forward or reverse movement of the tanker, such as flotation compelled, which dis turbs a pre-alinement of the hose coupling means to the manifolds, in the directions laterally of the boom construction, can be corected by lateral shifting of the trolley beam. With respect to the structure of FIGURES 1 and 5, the trolley beam and worm control for the hose cables 38, through brackets 35, will afford such a lateral adjustment of the hose. Referring again to FIGURE 5, and with additional reference to FIGURE 1, it will be noted that trolley beam brackets 35 for the hose lifting cables 38, carry, as to each bracket, a housing which encloses a drum 125, on which cable 38 is wound. As schematically shown only, in FIGURE 5 as to the left hand one of bracket 35, the shaft for drum has fixed thereon a gear 126 driven by bevel gear 127 on cable 37, the cable carrying an eye member 41 adapted to receive a rotary driving tool previously described and which is adapted for selected reverse rotation of drive cable 37.
